District Energy & Cooling Design

Criteria for Connecting To and Working On District Cooling Systems

District cooling provides customers with their HVAC requirements through a network of underground pipes. A district cooling plant distributes chilled water (approximately 44 to 45 degrees) to the customer's building through a set of heat exchangers that are located in the customer's mechanical room. A single plant can meet the cooling needs of several buildings. Austin Energy currently has district cooling systems in the central business district, the Domain, the Robert Mueller Municipal Airport Redevelopment Zone, and Austin Community College Highland Campus.

Follow our criteria, requirements, and guidelines when connecting to or working on district cooling systems to ensure your facilities are built properly.

The documents listed below will be updated annually and are for the current year. If you need earlier versions, email District Energy and Cooling Design.
